I read up a ton earlier at work and it said that it could be something simple as as a swollen hair follicle, clogged sweat pore, or something as advanced as swollen lymph nodes, which in itself could either be a simple infection or a bad as cancer.

Odd thing is, it wasn't there yesterday or the day before (I'm sure I would've noticed). Today my armpit was sore when I put on my deoderant.. thought that was kinda strange but didn't notice the lump till later on.

Only thing that's really changed lately aside from a badly sprained ankle about a month ago: I've been doin cardio everyday (30 mins) for about a week. So I'm guessin it's follicle/pore related.. no clue.

Anyway, haha I'm kinda freakin out. Wonder if anyone's had this or how common it is.. etc.

If it's a lymph node you will definitely feel a general but persistent only slightly painful gnawing of the node. Kind of like when your balls get played with just a little over the top. Think of lymph nodes as tiny little balls all over your body. In that they are similarly sensitive to manipulation...and the irritation I feel is very similar. They are smaller then a small marble even when swollen. If you find and manipulate the lump, I think you will know immediately that it is a lymph node. If this is a swollen or irritated lymph node, rest assured that any future lymph node pain will be quite apparent, as for me the irritation is consistent and identifiable.

I've had lumps in my pits before, but I'm prone to cysts and chalked them up to one of those. They head, then burst, or get burst by a lancing, drain and then get cleaned with h2o2 and everything's fine.

There used to be a topical ointment called icthymal that I think is no longer sold in the States, but it would draw out the contents of a cyst.

I routing for cyst or in-grown hair.

This happened to me once. I went to the doctor, he said it was an ingrown hair, poked it with a needle, squeezed it (ow...), and gave me antibiotics. Problem solved. I wouldn't worry about it... it's common. Have your doctor take care of it.

Hm, well it's too early to tell what it is, so in the meantime he gave me antibiotics and told me to check back in 5 days.

None of my other glands were swollen and I'm not insanely fatigued, so it's unlikely it's anything serious.

But daaaaaaamn it hurts. It's not feeling the way the lymph node was described above... but feels exactly like a bad zit would. The spot itself looks fine on the surface.. not red or anything. Just a lump.

Try quitting the deodorant for a while, especially if it includes antiperspirant.

Something similar happened to my wife, years ago. She ended up seeing a physician's assistant at the cut-rate medical clinic, a guy who'd been an army medic for a million years before retiring. He called it "Right Guard Armpit," and said it happened to some people who overused antiperspirants. Globules of sweat have a certain charge; your skin has an opposite charge, and that's what pulls sweat from your pores. Antiperspirants disrupt the skin's charge and keep the globules from being pulled out of the pore. Overuse of antiperspirants means the sweat _never_ comes out of those pores, they're never flushed clean, and well, you get a big white bump.

Anyway, couldn't hurt to stop antiperspirant for a while. If this was actually the problem, yes, maybe the cardio could be a factor; but only because your pits are trying to sweat desperately and the antiperspirant isn't letting them.
